Reconsidering physical key secrecy: teleduplication via optical decoding

Researchers from the University of San Diego (Benjamin Laxton, Kai Wang and Stefan Savage) developed Sneakey, a system that correctly decoded keys from an image that was taken from the rooftop of a four floor building. In this case the image was taken from 195 feet. This demonstration shows that a motivated attacker can covertly steal a victim's keys without fear of detection.
